Question 1.
What is the definition of a control volume?
Show hintHide hint
Think about areas where engineers analyze fluid behavior.
Question 2.
Define the mass conservation equation in fluid mechanics.
Show hintHide hint
It has to do with the balance of mass.
3Question 3.
What is the primary principle behind the mass conservation equation?
- Mass can be created

- Mass cannot be created or destroyed
Show hintHide hint
Think of a closed container.
4Question 4.
True or False: Incompressible flow means that density can change.
- True
- False
Show hintHide hint
Remember the definition of incompressibility.
Question 5.
Given a control volume representing a tank filling with water at a constant rate, derive the mass equation to describe the system, assuming constant density.
Show hintHide hint
Consider the inflow and the volume of water.
Question 6.
In a pipe experiencing pressure drop, analyze how mass conservation applies if the fluid is compressible and what implications it has on flow behavior.
Show hintHide hint
Pressure drop impacts density in compressible flows.
